Re: Device end to end processing time

The student mentioned ramdomly the wireless connection will stop working, wifi icon spin, and they have to input credentials again.

Were the credentials cached in the client?  Probably and if so, you should look for a rogue device impersonating your SSID, or less menacingly, someone thought it would be a good idea to turn on some sort of WiFi repeater, some brands of which seem to not realize that they cannot relay WPA-enterprise and do something weird by broadcasting a WPA-personal version of your beacon or some crap... never did figure out what exactly those peices of garbage thought they were doing.
